Lactobacillus rhamnosus GG (LGG) is a bacteria that was isolated in the 1980s from the gastrointestinal tract by research professors Sherwood Gorbach and Barry Goldwin, hence the suffix letters GG.
Since that time Lactobacillus rhamnosus GG has been one of the most widely studied probiotic strains and is used in a variety of commercially available probiotic supplements.
Probiotics are bacteria and yeast that are good for you, especially benefitting the digestive system. Lactobacillus rhamnosus GG was identified as a commercial probiotic strain because of its resistance to acid and bile, good growth characteristics, and a capacity to adhere to the gut wall .
The ability to ‘stick’ to the intestinal cell wall prolongs the persistence of a probiotic in the intestine and allows it to exert its helpful effects longer.
Health benefits for supplementing LGG include the prevention and treatment of gastro-intestinal infections and diarrhoea, promoting a healthy immune response, improving neural function, reducing inflammation, combating allergies and assisting weight loss .
LACTOBACILLUS RHAMNOSUS GG BENEFITS
LACTOBACILLUS RHAMNOSUS HELPS PREVENT DIARRHOEA AND GI INFECTIONS
Because of its excellent adhesion properties in the gut, LGG has been shown to help prevent and treat gastrointestinal infections and diarrhoea. LGG reduces the duration of diarrhoea in children , and significantly reduces the duration of diarrhoea symptoms in healthy adults taking antibiotics .
Administering probiotics containing LGG in hospitals has been shown to prevent patients contracting clostridium difficile infections . Clostridium difficile is a bacterium that can infect the bowel and cause diarrhoea.
LACTOBACILLUS RHAMNOSUS FOR IMMUNITY
It is believed that probiotic microorganisms, especially LGG, have the ability to modulate the immune system. LGG increases the response of the body’s white blood cells, T-lymphocytes, to search out and destroy pathogens .
LGG reduces the pro-inflammatory chemicals produced in the body during an infection, and at the same time increases the anti-inflammatory response .
Lactobacillus rhamnosus LGG enhances the gut barrier defence against invading pathogens to help prevent infection .
LACTOBACILLUS RHAMNOSUS IMPROVES DIABETES
Insulin resistance is the driving factor that leads to type II diabetes. Supplementing with Lactobacillus rhamnosus LGG has been shown to increase insulin sensitivity and decrease the risk of hypoglycaemia , where blood sugar levels fall to below normal levels.
LACTOBACILLUS RHAMNOSUS GG AIDS WEIGHT LOSS
Research tells us that there is a difference in gut bacteria between the overweight and those of healthy weight .
One study investigated the impact of Lactobacillus rhamnosus supplementation on weight loss and maintenance in obese women and found they were able to achieve sustainable weight loss .
LACTOBACILLUS RHAMNOSUS GG HELPS WITH DEPRESSION AND ANXIETY
A growing body of literature has demonstrated bidirectional signalling between the brain and the gut microbiome , effectively meaning that the gut and the brain talk to one another. Studies have shown that Lactobacillus rhamnosus can positively help with symptoms of depression and anxiety .
LACTOBACILLUS RHAMNOSUS IMPROVES IRRITABLE BOWEL SYNDROME (IBS)
The role that probiotics play in relieving irritable bowel syndrome (IBS) has been demonstrated, but the mechanism remained unclear.
However, supplementation with Lactobacillus rhamnosus GG was found to increase the production of serotonin in the gut . Serotonin is a chemical that has a wide variety of functions in the human body and low levels can affect gut function. It is sometimes called the happy chemical, because it contributes to wellbeing and happiness.
LACTOBACILLUS RHAMNOSUS PREVENTS ECZEMA AND FOOD ALLERGY
A Lactobacillus rhamnosus supplement was found to prevent the development of eczema in a group of high risk children . Even after ceasing supplementation, children show a significantly reduced prevalence of eczema.
Lactobacillus rhamnosus GG recently hit the news after it was successfully used to treat peanut allergy. Further investigation in to how it can be used to treat severe food allergy is underway.
LACTOBACILLUS RHAMNOSUS IMPROVES DENTAL HEALTH
Lactobacillus rhamnosus has been shown to improve dental health by keeping the numbers of bacterium called Streptococcus mutans in check in the oral cavity . Streptococcus mutans are a known cause of tooth decay.
LACTOBACILLUS RHAMNOSUS AND CANDIDA
Candida is a type of yeast found in the mouth, intestinal tract and vagina. When it grows to excessive amounts in the gut, it can contribute to food sensitivities, leaky gut syndrome and a host of other negative physical and mental conditions. LGG probiotics may help keep levels of candida in check.
Supplementing with Lactobacillus rhamnosus has also been shown to significantly increase the effectiveness of pharmaceutical treatments of vaginal candidiasis .
LACTOBACILLUS RHAMNOSUS IS BENEFICIAL DURING PREGNANCY
Establishment of a healthy gut microbiota at birth helps a newborn to develop a well-functioning immune system.
A prevalence of the species Bifidobacterium is associated with a healthy microbiota in newborn babies, and mothers that supplement Lactobacillus rhamnosus during pregnancy help the transfer and establishment of bifidobacteria in the gut of their babies. In addition, L. rhamnosus GG consumption increased the bifidobacterial diversity in infants 
EFFECTIVE SUPPLEMENTATION OF LACTOBACILLUS RHAMNOSUS
It is always beneficial to digestive health to include probiotic foods within your diet, as these can help with nutrient absorption and support the immune system.
Probiotic foods include kefir, fermented vegetables such as sauerkraut and kimchi, kombucha and yoghurt.
A colony forming unit is used to quantify how many bacteria in a probiotic are capable of dividing and forming colonies. Generally, 5 billion colony forming units (CFU’s) per day for children and 10 billion/day for adults of Lactobacillus LGG are associated with more significant study outcomes .
Inessa Advanced Daily Biotic delivers 10 billion CFU’s guaranteed to expiry date of Lactobacillus rhamnosus GG in advanced day release capsules proven to improve probiotic survival and delivery.
Inessa Advanced Biotic capsules also contain the amino acid glutamine, which is a vital nutrient for the intestines to rebuild and repair. They are also suitable for those using the low FODMAP diet.
